104 Digitizer Command Reference
*SRE < unmask > specifies which bits of the Status Byte Register are enabled
(unmasked) to generate a IEEE-488.1 service request. Event and summary bits are
always set and cleared in the Status Byte Register regardless of the unmask value.
unmask is the sum of the decimal weights of the bits to be enabled allowing these
bits to pass through to the summary bit RQS (bit 6 in the status byte).
The query form returns the current enable unmask value.
